I'm farsighted, so I can only conclude that I spent too much time outdoors as a kid. See Mom!?

If you get this type of short sight vision, you can train your eyes to get the vision back as this is caused by the eyes strength.
But if you have the type that has to do with your eye shape going outside will do nothing, and you can exercise it away
Yes, I spent 6 months in ICU in 2014, I had a lot of eye issues while I was there not related to my reason for my stay (bilateral lung transplant) but as side effects of procedures and meds but I also basically lost my depth perception unless it was directly in front of me. Living in a 10x10 room for half a year with no far away distances to observe made my eyes weak, it took about six months after I got home to get my full depth prescription back. Indoors just makes your eyes weak, mine is an extreme example, but it doesn’t permanently ruin them.
I was outside a lot and still got myopia :3
Then you were likely genetically predetermined to be at least a little myopic, but if you spent less time outside during your developmental phases you would likely be even more nearsighted than you are now.
Congrats on the luck
Same for me, I spent most of my free time as a child playing outside. I grew up in California, weather wasn't a concern, I was outside year-'round. I got my first pair of glasses at age 21. I suspect it's far more genetic than environmental.
Is this really causation though? Could it not just be that kids that spend less time looking at screens are less likely to be short-sighted AND more likely to spend time outside?
If this is just a correlation this would have to be a correlation at the population level. Countries where kids start school later on (e.g. 7 years old) have significantly lower rates of myopia than countries that start school early on in a child's development (e.g. 3 years old). It's still possible that this is a correlation, but the correlation would have to be capturing something deeper than just an individual kids screen time. Granted, this correlation would still need to account for differences between individual kids, but it would also need to account for differences between kids at a population level. It's hard to see what could be causing this correlation though. So maybe there's something there we're just not seeing, but at a certain point though the idea that there is a causal relationship starts to seem like the most plausible explanation for explaining this data
It wasn't mentioned in this article, but I remember reading somewhere that it might be because exposure to sunlight affects vitamin D production, which affects the length/shape of our eyeballs as we're growing up.
Another idea is that when you're outside, you spend more time focusing on objects further away, which helps develop those eye muscles
did not seem to help me. I guess I got the bad side of the coin flip.
Ysk 0*infinity = 0
If you spend no time doing anything that you ought to do (exercise, go outside, eat healthy) the immediately observable effects from any amount of sustained practice is measurable.
LMFAO
My mom blamed us (me and my older brother) for "sitting too close to the TV"
She kept us mostly locked indoors in an apartment (besides going to school) from the beginning of my memory up till 8 years old.
Then we moved to the US and from 8 to 12 I was in school from morning (like 7 AM maybe? forgot the exact time) till like 6PM cuz she signed me up afterschool programs cuz she wanted to use it as free babysitting essentially so she can work longer...
And we cant go outside alone without adults.
In China it was "a lot of kidnappers on the street thay will traffic you and sell your organs"
In the US it was "if you go outside without an adult, CPS will take you away and you can't see mama again" (idk why mom spoke in 3rd person sometimes lol)
Yay! so... from birth to 12 I was indoors, either in school or at home, most of the time...
outdoor time was rare and only when parents have a day off or like the 15 minutes of recess in school...
that's basically our outside time...
In China we had maternal grandma that sometimes took us outside...
In the US, it was just mom, dad, older brother, and me (cuz grandma can't come yet, no visa yet)... So we had even less outside time... like parenrs had to work all the time...
But of course its always "too much screens!" to be blamed lmao
From 8 to 12 was when my nearsightedness really developed a lot.
I didn't understand why I had nearsigntedness at the time, but now looking back and analyzing my life, now it's so obvious why lol..
My older brother has like -9.00 or -10.00 in the nearsightedness thing. Its funny my parents called it like 900 or 1000 "degrees".... like it sounds so much scarier when they drop the decimal point and literally say: "you're about to have ONE THOUSAND DEGREES IN NEARSIGHTEDNESS! You're gonna GO BLIND!"
